Fastest to T1 and T2?

I was wondering if anyone knew where I could get some information about the number of years it took schools to jump Tiers since their inception? Any schools Tier 4 to Tier 3 in 1O years? ( I hear FIU and Chapman have done it) Tier 3 to Tier 1 (no idea what schools here)? Thanks

Quinnipiac as only been accredited since the mid 90s. They were T4 until only the last few years, not sure when exactly they became T3...

Edit: Quinnipiac moved into the third tier as of 2006 (the 2007 rankings).

And they are already up to 108 from 116 last year. I wouldn't be surprised if they hit 2nd Tier within the next few years... but to be fair, Quinnipiac didn't just start in the 90s... it was University of Bridgport Law School for years before then.... it just didn't switch to the Quinnipiac campus or take the Quinnipiac name etc. until it was bought in the 90's... interesting thing is it is the first law school to switch like that without any interruption in the accrediation process
